Board:kontron/986lcd-m

The wiki is being retired!

Documentation is now handled by the same processes we use for code: Add something to the Documentation/ directory in the coreboot repo, and it will be rendered to https://doc.coreboot.org/. Contributions welcome!

This page describes how to use coreboot on the Kontron 986LCD-M/mITX mainboard. It is maintained by Uwe Hermann.

Status

Device/functionality	Status	Comments
CPU
CPU works	OK	Intel(R) Core(TM)2 CPU T5300 @ 1.73GHz (dual core)
L1 cache enabled	OK	CPU: L1 I cache: 32K, L1 D cache: 32K
L2 cache enabled	OK	L2 cache: 2048K
L3 cache enabled	N/A
Multiple CPU support	N/A
Multi-core support	OK	Both cores show up in /proc/cpuinfo.
Hardware virtualization	?
RAM
EDO	N/A
SDRAM	N/A
SO-DIMM	N/A
DDR	N/A
DDR2	OK	Works fine, but currently you need to populate both RAM slots with DIMMs (of the same size?).
DDR3	N/A
Dual channel support	N/A
ECC support	?
On-board Hardware
On-board IDE 3.5"	OK
On-board IDE 2.5"	N/A
On-board SATA	OK	Tested: SATA disk (hda1 in FILO, /dev/sda1 in Linux), but you currently have to use acpi=off or pci=noacpi.
On-board SCSI	N/A
On-board USB	OK	Tested: USB thumb drive in all 4 backpanel USB ports, as well as on the USB pin headers on the board (USB6_7, see manual).
On-board VGA	OK	You need to prepend the VGA blob from the proprietary BIOS for this to work. Console works, X11 works (use the intel X.org driver).
On-board Ethernet	WIP	The eth1 interface (in this case) works fine, but so far ifconfig -a only shows one of the three NICs (?)
On-board Audio	WIP	Doesn't seem to work, yet.
On-board Modem	N/A
On-board FireWire	?
On-board Smartcard reader	N/A
On-board CompactFlash	Untested	There's an onboard CompactFlash slot on the back-side of the board.
On-board PCMCIA	N/A
On-board Wifi	N/A
On-board Bluetooth	N/A
On-board SD card reader	N/A
Add-on slots/cards
ISA add-on cards	N/A
Audio/Modem-Riser (AMR/CNR) cards	N/A
PCI add-on cards	?
Mini-PCI add-on cards	Unknown
Mini-PCI-Express add-on cards	Unknown
PCI-X add-on cards	Unknown
AGP graphics cards	N/A
PCI Express x1 add-on cards	N/A
PCI Express x2 add-on cards	N/A
PCI Express x4 add-on cards	N/A
PCI Express x8 add-on cards	N/A
PCI Express x16 add-on cards	?
PCI Express x32 add-on cards	N/A
HTX add-on cards	N/A
Legacy / Super I/O
Floppy	?
Serial port 1 (COM1)	OK
Serial port 2 (COM2)	?
Parallel port	OK	Doing modprobe ppdev works, but no further test were performed.
PS/2 keyboard	OK
PS/2 mouse	OK
Game port	N/A
Infrared	?
PC speaker	OK
DiskOnChip	N/A
Input
Trackpoint	N/A
Touchpad	N/A
Fn Hotkeys	N/A
Fingerprint Reader	N/A
Laptop
Docking VGA	N/A
Docking LAN	N/A
Docking USB	N/A
Docking Audio	N/A
Docking Displayport	N/A
Thinklight	N/A
Webcam	N/A
Miscellaneous
Sensors / fan control	OK	Works fine using the w83627hf and coretemp Linux kernel modules.
Hardware watchdog	OK	Not yet actually tested, but it seems to be found: iTCO_wdt: Found a ICH7 or ICH7R TCO device (Version=2, TCOBASE=0x0560).
SMBus	?
CAN bus	N/A
CPU frequency scaling	?
Other powersaving features	N/A
ACPI	?
Reboot	?
Poweroff	?	Needs ACPI, thus won't work if you use acpi=off on the Linux kernel command line.
Suspend	Unknown
Nonstandard LEDs	N/A
High precision event timers (HPET)	OK	The HPET is detected by Linux (hpet0: at MMIO 0xfed00000, IRQs 2, 8, 0) and powertop output suggests that it works ok.
Random number generator (RNG)	N/A
Wake on modem ring	N/A
Wake on LAN	Untested	The board should support WOL according to the manual.
Wake on keyboard	?
Wake on mouse	?
TPM	Unknown
Flashrom	OK	Works fine, but you have to use -m kontron:986lcd-m when booted with the vendor BIOS (not needed when booted with coreboot).

Build tutorial

$ svn co svn://coreboot.org/repos/trunk/coreboot-v2
$ cd coreboot-v2/targets
$ ./buildtarget kontron/986lcd-m
$ cd kontron/986lcd-m/kontron_986lcd_m

Now copy your payload into the current directory and name it payload.elf. Then:

$ make -s

The resulting coreboot.rom is your coreboot ROM image you can flash using flashrom.

Notes

• If you use FILO, SATA will probably be hda and hdb, while hdc is the master drive of the IDE controller.
• Currently you have to use acpi=off on the kernel command line to make IDE work.
• If you experience kernel crashes try to blacklist the agpgart and intel_agp kernel modules.
• TODO: Add notes for proper (onboard) VGA setup.
